VENT-PLUG.

SPECIFICATION forming part of Letters Patent'No. 284,479, dated September 4, 1883. Application tiled May 24, 1883. (No model.)r

To @ZZ whom itmay concern.: i

Be it known that I,FRIEDEIIGII W. POLLE, of Greenville, in the county of Washington and State of Mississipphhave invented a new and useful Improvement in Bungs and Vents; and I do hereby declare that the following is a full, clear, and eXact description of the invention, which will enable others skilled in the art to which it appertains to make and use it, refer ence being had to the accompanying drawings, forming a part thereof. l

My invention relates to a vent-plug for beerbarrels and other liquor-vessels,` and it consists in the parts which will be hereinafter described, and pointed out in the claims.

, 'In the accompanying drawings, Figure 1 represents a central vertical section of the device with the round-head cap thereon. Fig. 21s' also a vertical section. In this view the round head is removed and the lever-cap substituted. Fig. 3 is a plan view, showing the lever and the cap in which it is mounted.

L Like letters indicate like parts throughout the views. L

A represents the plug, provided with a central continuous opening of two dierent diameters-viz., Band C-and a shoulder, a.

E is a spiral spring in the central opening orchamber, C, the lower end of said spring resting on the shoulder a, while its upper end surrounds the valve F and bears against the head F of the latter. y

;G is a valve-cap, having a circular flange or rim threaded on the inside and outside. rIhe inside threads of said cap screw onto the top part of the plug, which has surface threads adapted to receivethem. The outside threads of the valve-cap are adapted to receive either the threads onthe round-head cap or those on the lever-cap, all of which will be more fully hereinafter specified. 4The cap G is provided with a dish-shapeddepression, G', on its under side, into which the valve-head F' iits.

GZ is a bevel depression. G Glcommunicate and form an opening in the capG. i

H is a cap in which is mounted the lever I. H is an opening in the crown of cap H, to admit the working of theinner endof the'lever.

i H2 is a lever opening in the cap H, to admit the plunger-rod K. Said rod is pivoted at L to the forward end of the lever. The lever is fulcrumed at J in the cap H. H3 is a slot in the said cap to admit the lever.

y M is a round-head cap, adapted to screw over the valve-cap G. The cap Mis only used when the plug is driven into place. It is then removed and the lever-cap substituted.

The operation of the device is as follows: Assuming the plug A to b e in the barrel and provided `with the part-s shown in Fig." 2, when thus arranged vent may be giventhe vessel by simply' raising the lever I. Such action will force the plunger K onto the head F', thus depressing the spring E and valve F. A continuous opening is thereby made through the chambers B and C, and thence through the openings in the caps Gand H. The head F of the valve` operates as the vent opening and closing medium, and it is operated4 by the lever-plunger, as shown.

What I claim isl. Avent-plug provided with a central continuous opening and a shoulder, a, in combination with a spring, E, and valve F, the cap G, having openings G G2, and a cap, M, substantially as set forth.

2. A vent plug provided with a central opening of different diameters, a valve and spring, and avalve-cap having a valve-seat and opening, as described, in combination with a cap, H, lever I, and plunger K, substantially as set forth. l

3. Avent-plug having a central opening, B C, spring E, valve F, with head Ff, and the cap G, provided with beveled opening Gr2 and diskshaped opening G', `in combination with, the cap H, lever I, and plunger K, substantially as set forth. f

In testimony that I claim the foregoing I append my signature.
